Strictly classed

A new music classification system for MP3 files has proven to be a more accurate method than previous efforts. The difference with the new approach to classifying music is that it relies on a neural network program.

The artificial neural network mimics the behaviour of clusters of brain cells. Using a neural network involves training the system to build an audio profile of each music genre based on its beat and tempo.

According to the researchers, Mao-Yuan Kao and Chang-Biau Yang of National Sun Yat-sen University Shyue-Horng Shiau of the Chang Jung Christian University, most music fans can put a tune into a particular genre even on a first listen. However, for archivists and others with large collections of unclassified music, an automated approach that assigns the main genre to each tune would save a lot of time and effort.

The team has so far tested their approach on a collection of several hundred ballroom dance music files, such as the cha-cha-cha, jive, quickstep, and tango. Although this approach was not 100 per cent accurate, it has outperformed the existing – Ellis and Dixon – methods.

However, the team suggest that the neural network will need further training to be able to classify more diverse music collections such as classical, jazz, pop and so on.

The research is published this month in the International Journal of Intelligent Information and Database Systems.

Why we are shutting children out of classical music
I am a 33-year-old classical music critic. In my 25 years of going to concerts (and since my 20s, writing about them), I am almost always the youngest person in the audience. Everywhere I go, from Bournemouth to Inverness, concert halls and opera houses resemble conventions for the blue-rinse brigade. Another thing: I've noticed that bus and train stations now pipe canned classical music, day-in, day-out, through their speakers as a way of stopping young people hanging around. So toxic have the associations become, that this experiment actually works: there is evidence that playing Beethoven and Mahler has reduced antisocial behaviour on the transport network. An entire generation, aged between 10 and 30, seems radically disenfranchised from classical music. How, and when, did this happen?

Monteverdi: Madrigals Book 7; Delitiae Musicae/Longhini
By the time he published his seventh book of madrigals in Venice in 1619, Monteverdi had left the standard Renaissance madrigal form far behind. He signalled the change in his approach by subtitling the new collection "concerto", omitting conventional five-voice madrigals altogether, including among the 32 musical numbers instrumental pieces and settings of texts for forces ranging between a solo voice and a quartet, and ending with the Ballo, Tirsi e Clori, a quasi-operatic sequence of solo and two-part madrigals and choruses. It's a huge, teemingly inventive and experimental collection that Delitiae Musicae present in Marco Longhini's performing edition. Both the vocal forces and the instrumental commentaries are beautifully varied in his performances, which involve more than 20 musicians; this group's Monteverdi series continues to be one of the highlights of the Naxos catalogue and an outstanding bargain.
